Akoustis 5.2 GHz WiFi BAW RF Filter for Routers to Start Shipping Soon

In March 2018, Akoustis Technologies introduced the first commercial 5.2 GHz BAW RF filter for tri-band WiFi applications.

The AKF-1252 filter is produced using Akoustis’ proprietary XBAW manufacturing process, which delivers high-performance RF filter solutions for frequencies up to 7 GHz to address critical RF filter requirements for existing and next-generation communications applications, including the emerging 5G mobile network.

The Company began sampling a limited number of potential customers, seeking technical feedback and gauging market interest. Thereafter, Akoustis engaged in internal engineering efforts to incorporate customer feedback into the AKF-1252 product design.

In late August 2018, Akoustis completed final engineering modifications to the AKF-1252 5.2 GHz BAW filter - achieving a final locked design which is currently undergoing product qualification to support mass production under the Company’s quality management system (QMS).

By mid-September 2018, Akoustis delivered AKF-1252 filter evaluation boards (EVBs) to more than one dozen potential customers, including OEM, ODM, System-on-Chip (SOC) and RF module manufacturers. The Company expects the first order for WiFi router applications by the end of Q4 CY18.

Akoustis has received its first purchase order from the Company’s RF distributor partner to support resale activity. Shipments toward this order are expected to occur by the end of the current calendar year. Capacity planning is on-going within the Company’s New York Wafer Fab to support in-house filter manufacturing using the Akoustis’ first generation XBAW process (called XB1).

The AKF-1252 provides a low insertion loss covering U-NII-1 and U-NII-2A bands and meets the stringent rejection requirements enabling coexistence with U-NII-2C and U-NII-3 bands. The industry-leading high-power rating satisfies the demanding requirements of the latest WiFi standards including 802.11ax. The filter solution incorporates standard commercial module packaging and is compatible with high-volume, lead-free SMT soldering processes.

The AKF-1252 is a high performance, ultra-small BAW RF filter with a 5.2 GHz passband designed for use in tri-band WiFi router applications.

The AKF-1252 Filter Product Features:

  • Ultra small form factor 2 x 2.5 x 0.9 mm
  • Single-ended Tx/Rx ports
  • High rejection enables co-existence with adjacent WiFi UNII bands
  • High power rating, maximum +30 dBm
  • Low insertion loss passband filter
  • Performance over -40 C to +85 C
  • RoHS compliant, Pb-free package
